6/ Key Takeaways 📌
Primitives (int, double, bool, String) → Passed by value (copy).
Objects (List, Map, custom classes) → Passed by reference (modifies original).
To avoid accidental modifications, create copies or use immutable structures.

4/ Why does this matter? 🤔
If you modify objects unintentionally, you might introduce unexpected side effects in your code. This is especially important in:
✔️ Flutter state management
✔️ API responses
✔️ Multithreading & concurrency

3/ On the other hand, objects like:
List
Map
Set
Custom classes
are passed by reference. Instead of creating a copy, Dart passes a reference to the original object. This means modifications inside a function affect the original data.

2/ Primitive types in Dart include:
int
double
bool
String
These are passed by value, meaning when you pass them to a function, a copy is created. Changes inside the function don’t affect the original variable.
